"Attach public link to personal file" does not respect custom ports

Hey,

Thanks for this add-on, it's fantastic!

I recently came across a bug where when I add a personal file with "Append public link to personal file" to the title, the dedicated port I use for my Nextcloud installation is not respected.

My nextcloud is available at https://my-domain.com:5001 available, but when I use "Attach public link...", it adds

https://my-domain.com/s/XXXXXXXXXXXXXXX

instead of

https://my-domain.com:5001/s/XXXXXXXXXXXXXXX

to the title.

Thanks for your help in advance!
